To all whom it may concern..-

Be it known that we, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY, all subjects of Her Majesty the Queen of Great Britain, residing at Castleton, in the county of Lancaster, England, have invented a certain new and useful Improvement in Electric Stop-Motion Drawing-Frames, of which the following is a specification.

This invention comprises a new and improved construction and arrangement Of parts for supporting the calender rollers, the tinted rollers, theback plate, (whichcarriers the top clearer and cap bar,) the electricrroller and guide rail. the Object being to insure steadiness in the Working and provide for the simultaneous adjustment of the various related parts.

In the accompanying drawings Figure l is a sectional end elevation illustrating the improvements in electric stop motion drawing frames. Fig. 2 is a portion of the frame illustrating a modification.

According to Ourinvention we construct the frame or support 1 for the variousparts which is T headed 'in section so as to provide for carrying the tinted rollers 3, 3, 3', 3', and sliding bracket 4,(on which are fixed the back plates 5I and the guide rail 6,) the calender roller 2 and the insulated calender roller 2A. The calender rollers are carried On an exten- The sliding 8 and has two arms or projections 9, 10 one of which arms 9 supports the guide rail6 the other arm 10 supporting the back plate -5 which carries the top clearer 11 and `cap bars 12 for the electric top roller 13.: The said block plate 5`is insulated at 14' from the projection 10 Of the sliding bracket 4 and on moving the sliding bracket 4 the latter carries the top clearers 11, cap bars 12, electric rollers 8-13 and guide rail 6, and all the parts are moved simultaneously and without disturbance of their relative positions, it only being necessary to loosen the nut 15 and move the sliding bracket 4 along the top Of the frame 1 to the required position and then tO tix it there by tightening the nut 15. Or the arm 9 may be carried by the support 1 by the 5o block 9 as' shown in- Fig. 2 so that the guide rail r6 may be independently adjusted.

The bearings 17 for the drawing rollers 3', 3 are mounted on the supports-1 so as to be readily replaced in place of being cast to and 5 5 formi-ng part of the support as formerly.

With this arrangement it will be seen that a simultaneous adjustment Of the back plate, electric rollers and guide rail may be more readily and efficiently obtained, as the arms 6o 1. In electric kstop motion drawing frames 7o and in combination the support 1, adjustable sliding bracket 4 carried thereby, guide rail 6, insulated back plate 5, top clearer 11, cap bar 12 and rollers 8, 13, all carried by the bracket 4, substantially as and for thepur- 75 pose described.

2. In electric stop motion drawing frames and in combination the support 1, adjustable sliding bracket 4 carried thereby, insulated back plate 5', top clearer 11', cap. bar 12, and 8o rollers 8, 13, all 'carried by the bracket 4 substantially as and for the purpose described.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
